一、导入csv文件
1、创建导入页面
<!DOCTYPE html>
<html lang="zh-CN">
<meta charset="UTF-8">
<head>
<title>文件提交表单</title>
</head>
<body>
<form action="test5.php" method="post" enctype="multipart/form-data">
<label for="file">选择文件:</label>
<input type="file" name="file" id="file">
<input type="submit" name="submit" value="导入">
</form>
</body>
</html>2、导入后端处理test5.php
<?php
/**
* $filename 文件
* $lineOne 是否显示标题
*/
function parseFile($filename,$lineOne=false) {
if (!$filename) {
die("未选择文件");
}
$file = fopen($filename, 'r');
$arr = [];
$i=0;
while ($line = fgets($file)) {
$i++;
if($i==1&&!$lineOne){
continue;
}
$line = rtrim($line, "\n\r\0");
$encoding = mb_detect_encoding($line, ['utf-8', 'gbk', 'latin1', 'big5']);
if ($encoding != 'utf-8') {
$line = mb_convert_encoding($line, 'utf-8', $encoding);
}
$arr[] = explode(',', $line);
}
return $arr;
}
$filename = $_FILES['file']['tmp_name'];
$result = parseFile($filename);
print_r($result);
二、导出csv文件
<?php
$output = fopen('php://output', 'w');
header('Content-type: application/csv;');
header('Content-Disposition: attachment; filename="测试——' . date("YmdHis", time()) . ".csv");
fputcsv($output, [
iconv('UTF-8', 'GB2312', "标题"),
iconv('UTF-8', 'GB2312', '哈哈'),
]
);
fputcsv($output, [
iconv('UTF-8', 'GB2312', "名称"),
iconv('UTF-8', 'GB2312', "年龄"),
iconv('UTF-8', 'GB2312', "生日"),
]
);
$data=[
["name"=>'小明','age'=>'22','date'=>'1994-01-12'],
["name"=>'小a','age'=>'12','date'=>'1994-01-33'],
["name"=>'小b','age'=>'33','date'=>'1994-01-22'],
["name"=>'小c','age'=>'21','date'=>'1994-01-22'],
["name"=>'小d','age'=>'11','date'=>'1994-01-12'],
["name"=>'小e','age'=>'22','date'=>'1994-01-12'],
["name"=>'小e','age'=>'33','date'=>'1994-01-01'],
];
foreach ($data as $value){
fputcsv($output, array(
iconv('UTF-8', 'GB2312', $value['name']),
"\t" . $value['age'],
"\t" . $value['date'],
)
);
}
